Description

A kind of high efficiency cement composite grinding additive and production method thereof
Technical field
The invention belongs to the cement technology field, particularly cement grinding aid.
Background technology
In the grinding process that Cement industry is produced, add a small amount of grinding aid, can consume under the identical condition with mill power in the fineness of cement and increase output, also can under the cement output condition identical, increase the specific surface area of cement, thereby improve cement intensity and quality with mill power.Yet commercially available grinding aid has liquid and two kinds of powdered, and wherein Ye Tai grinding-aid effect is better, and morning by force, reinforced effects is not obvious; Early potent fruit is better for powdered, and late-enhancement and grinding-aid effect are not obvious.Since cement new-standard was implemented, some cement production enterprises utilized industrial residue to produce complex cement as much as possible, and need to adopt the compound grinding aid of powdery in order to give full play to the high advantage of clinker strength.Therefore, select suitable industrial residue, utilize its activity excitation performance, produce strengthen and grinding-aid effect all good, cheap solid or liquid grinding aid are to have developed not only early by force, strengthened but also one of the trend of the multifunctional assistant grinding agent of product is put forward in grinding aid.
Summary of the invention
In order to solve present liquid grinding aid is that grinding-aid effect is better, little to improving cement early strength and later strength effect; Early potent fruit is better and the powdery grinding aid is, grinding aid effect and the inapparent technical problem of cement late-enhancement effect, provide a kind of grinding-aid effect good, not only made cement early by force but also can late-enhancement, and to different varieties cement adaptability efficient compound grinding aid and production method thereof preferably.
To achieve these goals, propose following technical scheme 1: a kind of high efficiency cement composite grinding additive, its special character are the raw materials that it comprises following mass percent: plaster of Paris 10-25, burning aluminite 10-30, Starso 20-40, trolamine 2-4, polyacrylate TH-1100 0.5-2, zeolite powder or flyash, slag, perlite powder 20-30.
Propose technical scheme 2 in order to improve dispersion effect, promptly increase dispersion agent NNO in such scheme, its mass percent is 0.5-3.
The above-mentioned plaster of Paris is the low temperature calcination gypsum, be with the plaster of paris after being crushed to the 1-3mm granularity, or phosphogypsum is added in the rotary kiln of indirect heating and calcines 15min, the material outlet temperature is 140-150 ℃, the gained grog is through pulverizing, obtaining by screening.Its main component is semi-hydrated gypsum CaSO 4 1/ 2H 2O.
Above-mentioned burning aluminite be with natural alumstone through the ripe aluminite of commodity that calcining makes, require its AL 2O 3Content is greater than 15%, SO 3Content is greater than 8%.
Above-mentioned Starso is commodity metasilicate pentahydrate sodium (Na 2SiO 35H 2O), require total alkali content (with Na 2The O meter) is no less than 28%.
Above-mentioned trolamine is the technical grade trolamine.
Above-mentioned polyacrylate is the commodity polyacrylate TH-1100 that Shandong Taihe Water Treatment Co., Ltd. produces, and this product is low-molecular-weight polypropylene acid (PAA) homopolymer and corresponding salt, for example sodium polyacrylate.
Above-mentioned dispersion agent (also claiming diffusant) NNO is that Shangyu, Zhejiang Province city opens the commodity dispersion agent of containing the production of chemical industry company limited, and chemical ingredients is mainly naphthalenesulfonateformaldehyde formaldehyde (methylene aldehyde sodium dinaphthalenesulfonate), and its molecular formula is C 12H 14O 6S 2Na 2
Above-mentioned zeolite powder is made by natural zeolite is levigate, and fineness requirement is 0.08mm, square hole sieve screen over-size≤15%.Utilize the dispersed carrier of making liquid starting material of its absorption.The fineness requirement of flyash, slag, perlite powder is identical with zeolite powder.
The production method of technique scheme 1 described high efficiency cement composite grinding additive, it comprises the steps:
1) choosing of raw material, by the specification of quality of each raw material and shared mass percent choose the plaster of Paris, burn aluminite, Starso, trolamine, polyacrylate TH-1100 and zeolite powder or flyash, slag, perlite powder be standby;
2) liquid starting material trolamine and polyacrylate TH-1100 are evenly dripped in zeolite powder or flyash, slag, perlite powder by liquor pump, and make the grinding aid enhancement component by powder stirrer or compound stirrer;
3) and the plaster of Paris, burning aluminite and Starso evenly add cone and screw mixer or the compound stirrer of chemical industry commonly used mixes stirring 20-30min with the grinding aid enhancement component by the batching mass percent, measure, pack promptly to get product of the present invention.
The production method of technique scheme 2 described high efficiency cement composite grinding additives, its special character is to increase dispersion agent when the choosing of the first step raw material of aforementioned production method, and in third step dispersion agent is added to mix in the mixing machine with other raw material and stirs.
High efficiency cement composite grinding additive of the present invention is when using, and its incorporation is 0.5% of a cement ingredient total mass.Incorporation can suitably increase when being used to produce masonry cement, few grog and clinker-free cement (gelling material), is generally the 0.5-1.0% of gelling material batching total mass.Its addition manner is gone into mill by setting volume by quantitative control.
Because grinding aid of the present invention adopts multicomponent raw material to be composited, therefore have ideal technical feature and economical effectiveness.
1) the grinding aid effect is outstanding, uses this product can improve mill hourly output 10-15%, reduces power consumption.
2) use this product can increase the flowability of cement granules, prevented the grinding phenomenon, can reduce the cement screen over-size, increasing specific surface area, make the grain composition of cement more be tending towards reasonable, thereby help the performance of intensity, cement three days and seven days ultimate compression strength are improved more than 20%, intensity improved 10-15% in 28 days.
3) carrier of this product is the zeolite powder of absorption good dispersity, but small amount of liquid raw material in the active adsorption split batch charging component and the moisture in the product prevent the product caking that makes moist.
4) use this product, produce equicohesive cement because the grog volume descends, the increase of blended materials such as flyash can reduce hydration heat and the free calcium oxide in the cement and the content of magnesia of cement, improves soundness.Therefore use this product very favourable with the grinding station of using shaft kiln clinker to the bad shaft kiln factory of grog stability.
5) volume of this grinding aid only is 0.5% of a cement amount, can reduce grog consumption 8-10%, the blended material of corresponding increase 7.5-9.5%; Can carry simultaneously and produce economize on electricity, thereby can reduce production costs, generally can make the cement unit cost reduce 5-10 unit,, cement cost is descended about 10 yuan the high area of minority grog cost.
6) use this grinding aid can increase the incorporation of industrial residues such as flyash, coal gangue, slag, slag, can effectively utilize local residue resource development manufacture of cement.Particularly, can obtain more remarkable economic efficiency and social benefit because of utilizing industrial residue for the enterprise that utilizes few grog such as this products production pulverized fuel ash cement, complex cement and masonry cement, clinker-free cement more.
7) because the production method of this product is that two kinds of liquid with main grinding aid enhancement are dripped respectively, mix in the dispersed carrier of absorption, preprocessing becomes the grinding aid enhancement component, makes the homogeneity of final batching and product good.
